I was taking a test. Problem was that the entire test was on a subject I did not study. I knew about half of the test's contents, but not in great detail. I was finishing it up, and then my pen stopped working. I freaked out and then cut my finger with the tip of my pen to continue writing answers on the test with my blood. I woke up after submitting the test.
I'm awake now, and I'm fairly certain I'll do well on today's test. No need to worry like this.
